Answer:
I’m not gonna show you a graph but these instructions should help…
For the first equation.
You have
5y = -3x + 15
So we have to put it in y=mx + b format.
We can isolate y.
Divide 5 on both sides.
y = -3/5 x +3
You have your equation right htere.
The y intercept (b) here is 3 following the format y=mx +b
So now you plot a point on (0,3) since thats your Y- intercept, first point of contact on the y axis. Now for the slope. Slope goes by rise / run. Think of it as you get out of bed, you have to get up first before you run off to whatever you do.
Now you can just follow the instructions give, -3/5 is -3 rise and 5 run. Since a -3 rise is going down, we do down since its a negative slope here.
Starting from (0,3) you go down 3 units, then at that point go to the RIGHT 5 units. You should have a plotted point on, (5,0). Now following the postulate, if two lines exists in a plane that a line is created, draw a line using the 2 points from (0,3) to (5,0). (Draw throguh the whole thing, not segment and make sure it fills up the whole coordinate plane)
That is your equation.
For the second equation its the same thing, but this time it’s an inequality.
It’s the same gist and the equation is already simplified due for you!
Start on the y- intercept which is -2, or (0,-2)
Now since it’s a positive slope, because its 1/2, rise 1, run 2. From (0,-2) rise up 1 and then run two units to the RIGHT.
You should end up with, (2, -1)
Construct a line throught he two points (not segment line, fill the whole plane).
Now since its an inequality, we don’t stop there.
It’s a less then sign so when constructed the line that fills the whole plane.
You have to shade the bottom RIGHT of your screen that has a line throguh it.
So basically a line is made though two points and you have the whole plane covered. Shade in the bottom part WITHOUT crossing over the line.

PLEASE HELP!
Answers
divide by 3.14 on both sides first.
V/3.14 = r^3
Now cube root both sides.
3√(V/3.14) = r
r = 3√(V/3.14)
r is the cube root of v/3.14.

an equilateral triangle has two sides given as (3x-2)cm and (18+x)cm what is the perimeter
Answers
Answer:
84 cm
Step-by-step explanation:
Equilateral triangle have sides that measure the same
so
3x-2 = 18+x
Subtract x from each side
3x-2-x =18+x-x
2x-2 = 18
Add 2 to each side
2x-2+2 = 18+2
2x= 20
Divide by 2
2x/2 = 20/2
x = 10
The side measures18+x = 18+10 = 28
The perimeter is 3 times the length of one side
3*28 = 84

Answers
Answer:
Distributive property
Step-by-step explanation:
Distributive property states that,
multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
That is,
a(b + c) = ab + ac
3 avocados cost $0.40 each
3x0.40
= $1.2
5 lemons cost $0.40 each.
5x0.40
= $2
Total = $1.2 + $2
= $3.2
Using distributive property
(3+5)0.40
= 8(0.40)
= $3.2
Answer: Distributive property
Step-by-step explanation:
The Distributive property is the same as a(b + c) = ab + ac

Answers
The probability that the John either hits a Bull’s eye or scores 10 points in the game of darts is 2/5.
What is probability?Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event. The probability of an event can not be more than the number 1.
John is playing a game of darts. In this game of dart,
The probability that he throws a dart into the center of the dart board (the Bull’s eye) is 1/10. The probability that he throws the dart into the 10-point ring is 3/10.The probability that he either hits a Bull’s eye or scores 10 points is equal to the sum of the probability he hits the bull's eye and the probability that he throws the dart into the 10-points ring.
Let, the probability that he either hits a Bull’s eye or scores 10 points is P. Thus,
[tex]P=\dfrac{1}{10}+\dfrac{3}{10}\\P=\dfrac{4}{10}\\P=\dfrac{2}{5}[/tex]
Hence, the probability that the John either hits a Bull’s eye or scores 10 points in the game of darts is 2/5.
